Diagnosis support system, method of controlling the same, and storage medium

Abstract

A diagnosis support system obtains input information corresponding to a case, identifies a diagnosis corresponding to the case based on the input information, obtains the inference probability of the diagnosis, and displays supporting information corresponding to the inference probability of the identified diagnosis on a display unit.

       1. A diagnosis support system comprising:
 one or more processors; and 
 one or more memories coupled to the one or more processors and having stored thereon instructions which, when executed by the one or more processors, cause the diagnosis support system to: 
 obtain input information corresponding to a case; 
 identify a diagnosis corresponding to the case based on the input information and obtain an inference probability of the diagnosis; 
 select at least one of affirmative information or denial information as supporting information for the identified diagnosis based on the inference probability of the identified diagnosis; and 
 display the supporting information of the identified diagnosis on a display unit, 
 wherein the affirmative information has an affirmative influence on the inference probability of the identified diagnosis, and 
 wherein the denial information has a denial influence on the inference probability of diagnoses other than the identified diagnosis. 
 
     
     
       2. The system according to  claim 1 , wherein the instructions, when executed by the one or more processors, further cause the diagnosis support system to obtain an influence degree of the input information with respect to the identified diagnosis, and
 wherein at least one of the affirmative information or the denial information is selected as the supporting information based on the influence degree. 
 
     
     
       3. The system according to  claim 2 , wherein the affirmative information having the influence degree which affirms the identified diagnosis is selected in a case where an inference probability of the identified diagnosis is higher than a predetermined criterion. 
     
     
       4. The system according to  claim 2 , wherein the denial information having an influence degree which denies diagnoses other than the identified diagnosis is selected in a case where the inference probability of the identified diagnosis is lower than a predetermined criterion. 
     
     
       5. The system according to  claim 2 , wherein the affirmative information having an influence degree which affirms the identified diagnosis and the denial information having an influence degree which denies diagnoses other than the identified diagnosis is selected in a case where the inference probability of the identified diagnosis is lower than a predetermined criterion. 
     
     
       6. The system according to  claim 1 , wherein the identified diagnosis is a diagnosis having a highest inference probability with respect to the diagnosis. 
     
     
       7. The system according to  claim 1 , wherein the identified diagnosis is identified by user designation. 
     
     
       8. A method of controlling a diagnosis support system, the method comprising:
 input information corresponding to a case; 
 identifying a diagnosis corresponding to the case based on the input information and obtaining an inference probability of the diagnosis; 
 selecting at least one of affirmative information or denial information as supporting information for the identified diagnosis based on the inference probability of the identified diagnosis; and 
 displaying the supporting information of the identified diagnosis on a display unit, 
 wherein the affirmative information has an affirmative influence on the inference probability of the identified diagnosis, and 
 wherein the denial information has a denial influence on the inference probability of diagnoses other than the identified diagnosis. 
 
     
     
       9. A non-transitory computer-readable storage medium storing a program for causing a computer to execute each step of a decision support method, the decision support method comprising:
 obtaining input information corresponding to a case; 
 identifying a diagnosis corresponding to the case based on the input information and obtaining an inference probability of the diagnosis; 
 selecting at least one of affirmative information or denial information as supporting information for the identified diagnosis based on the inference probability of the identified diagnosis; and 
 displaying the supporting information of the identified diagnosis on a display unit, 
 wherein the affirmative information has an affirmative influence on the inference probability of the identified diagnosis, and 
 wherein the denial information has a denial influence on the inference probability of diagnoses other than the identified diagnosis. 
 
     
     
       10. The system according to  claim 1 , wherein at least the denial information is selected as the supporting information of the identified diagnosis in a case where the inference probability of the identified diagnosis is lower than a predetermined criterion. 
     
     
       11. The system according to  claim 1 , wherein at least the affirmative information is selected as the supporting information of the identified diagnosis in a case where the inference probability of the identified diagnosis is higher than a predetermined criterion. 
     
     
       12. The system according to  claim 1 , wherein at least the affirmative information is selected as the supporting information of the identified diagnosis in a case where the inference probability of the identified diagnosis is higher than a predetermined criterion, and at least the denial information is selected as the supporting information of the identified diagnosis in a case where the inference probability of the identified diagnosis is lower than the predetermined criterion. 
     
     
       13. The system according to  claim 1 , wherein the affirmative information and the denial information is selected as the supporting information of the identified diagnosis in a case where the inference probability of the identified diagnosis is lower than a predetermined criterion. 
     
     
       14. A diagnosis support system for performing inference about diagnosis names, the system comprising:
 one or more processors; and 
 one or more memories coupled to the one or more processors and having stored thereon instructions which, when executed by the one or more processors, cause the diagnosis support system to: 
 obtain input information about findings; 
 calculate an inference probability of the diagnosis names based on the input information; and 
 display denial information on a display unit in a case where a calculated probability of a target diagnosis name of the diagnosis names is lower than a predetermined criterion, 
 wherein the denial information is related to the input information in which the probability of at least one of the diagnosis names other than the target diagnosis name is reduced. 
 
     
     
       15. The system according to  claim 14 , wherein affirmative information is displayed on a display unit in a case where the probability of the target diagnosis name is higher than the predetermined criterion, and
 wherein the affirmative information is related to the input information in which the probability of the target diagnosis name is increased. 
 
     
     
       16. The system according to  claim 14 , wherein the target diagnosis name is a diagnosis name having a highest probability. 
     
     
       17. The system according to  claim 14 , wherein the target diagnosis name is identified by user designation. 
     
     
       18. The system according to  claim 14 , wherein the instructions, when executed by the one or more processors, further cause the diagnosis support system to display a chart showing the inference probability of the diagnosis names.

 displaying denial information on a display unit in a case where a calculated probability of a target diagnosis name included in the diagnosis names is lower than a predetermined criterion, 
 wherein the denial information is related to the input information in which the probability of at least one of the diagnosis names other than the target diagnosis name is reduced. 
 
     
     
       20. The method according to  claim 19 , wherein the displaying includes displaying affirmative information on a display unit in a case where the probability of the target diagnosis name is higher than the predetermined criterion, and
 wherein the affirmative information is the input information in which the probability of the target diagnosis name is increased.
